Problems solved by technology

[0003] As the use time of concrete continues to grow, many concrete pavements need to be repaired or rebuilt on a regular basis. Before the repair process or remodeling, it is usually necessary to manually crush the concrete pavement with a hydraulic breaker, but during the concrete crushing process, it will produce a powerful break Vibration, for a long time, will cause pain in the hands of the operator or injury to the

Abstract

The invention belongs to the technical field of road construction, and specifically discloses a crushing and recycling vehicle for an old concrete pavement. The crushing and recycling vehicle comprises a motor tractor, an undercarriage, a crushing box, a cutting unit, a crushing unit, an atomizing unit and a cleaning unit, wherein the cutting unit comprises a drive motor, a rotating shaft and a blade; the atomizing unit comprises an air tank, a water tank and an atomizing pipe; the crushing unit comprises a mounting plate, a transmission shaft, a turbine, a cam, a connecting rod and a crushingrod; the blade is used for cutting the concrete pavement into a plurality of grooves, the concrete pavement is crushed under the left-and-right motion of the crushing rod, the atomizing unit is usedfor generating high pressure gas by using the reciprocating motion of a piston arranged on the crushing rod during cutting and crushing, water mist is generated under the effect of high pressure gas for reducing dust generated when the concrete pavement is cut. According to the crushing and recycling vehicle, the damage such as noise and dust generated in the crushing process of the concrete pavement is reduced by adopting layered cutting, crushing and stripping manners, and chippings and stone blocks are separated by using the difference of the weight of the chippings and the weight of the stone blocks, so that subsequent comprehensive utilization is facilitated.

Description

technical field [0001] The invention belongs to the technical field of road construction, in particular to an old cement road crushing recovery vehicle. Background technique [0002] Concrete is one of the most important civil engineering materials today. It is a kind of artificial stone made of cementitious materials, granular aggregates, water, and admixtures and admixtures added when necessary, prepared in a certain proportion, uniformly stirred, compacted, cured and hardened. Concrete has the characteristics of rich raw materials, low price and simple production process, so its consumption is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. These characteristics make it widely used, not only in various civil engineering, but also in shipbuilding, machinery industry, marine development, geothermal engineering, etc. Concrete is also an important material. [0003] As t...
